Description

Technical Field

[0001] The utility model relates to the field of preparation of organic chemical raw materials, and specifically relates to a device for extracting and separating components of organic chemical raw materials. Background Art

[0002] Organic chemical raw materials refer to the chemical substances required in the process of organic synthesis, and are usually also called organic synthesis reagents. These raw materials can be used to synthesize various organic compounds.

[0003] In the production process of organic chemical raw materials, there are usually extraction and separation steps. The purpose is to separate specific organic substances from the mixture to obtain pure components or products that meet specific requirements. There are various extraction and separation methods, including liquid separation (extraction), distillation, etc.

[0004] When separating hydrocarbon chemical substances, the existing distillation method will make it difficult to separate different hydrocarbon chemical substances when encountering hydrocarbon substances with similar boiling points, resulting in more impurities in the extracted organic chemical raw materials and affecting the purity. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for extracting and separating components of organic chemical raw materials, which effectively solves the problem that when separating and extracting hydrocarbon chemical substances with similar boiling points, the existing distillation method will cause more impurities in the extracted target organic chemical raw materials and insufficient purity.

[0006] The technical solution of the utility model is as follows:

[0007] A device for extracting and separating components of organic chemical raw materials includes a separation box. On the opposite inner surfaces of the separation box, there are latching platforms. The vertical cross-section of the latching platform is "L" shaped. An adsorption layer and a permeation layer are respectively arranged on the latching platform. The vertical cross-section of the adsorption layer is arc-shaped and the adsorption layer is located above the permeation layer. A top cover is arranged on the top of the separation box. A vertical feed pipe is arranged on the top cover. A shower head is arranged at the bottom of the feed pipe. The shower head is located inside the separation box and directly above the adsorption layer. A through discharge port is arranged on the inner wall bottom plate of the separation box.

[0008] Furthermore, outward limiting grooves are arranged on the opposite inner surfaces of the separation box. A clamping strip is arranged on the side of the latching platform close to the separation box. The clamping strip is inserted into the limiting groove.

[0009] Furthermore, a first latching groove and a second latching groove are arranged on the latching platform. A membrane shell one is arranged on the top of the adsorption layer. A grille is arranged at the bottom of the adsorption layer. The vertical cross-section of the grille is also arc-shaped. The grille and the membrane shell one fix the adsorption layer.

[0010] Furthermore, insertion plates are symmetrically arranged on both side walls of the first membrane shell, and the insertion plates are movably embedded into the first lapping groove.

[0011] Furthermore, the permeable membrane on the permeation layer is multi-layered. A second membrane shell is arranged outside the permeation layer. Lapping plates are arranged on two side walls of the second membrane shell. The bottom of the lapping plate forms a rear semi-circular part, and the semi-circular part is movably located in the second lapping groove.

[0012] Furthermore, an opening is formed on the surface of the separation box perpendicular to the lapping platform. The opening is located at the position of the permeation layer. A sealing plate is movably connected in the opening. An elastic sealing gasket is arranged on one side of the sealing plate close to the permeation layer, and a handle is arranged on the other side of the sealing plate.

[0013] Furthermore, inclined chutes are symmetrically formed on the inner bottom plate of the separation box, and the lowest point of the inclined surface of the inclined chute is located at the discharge port.

[0014] The advantages of the present utility model are as follows:

[0015] 1. By arranging an adsorption layer and a permeation layer inside the separation box of the present utility model, the mixture will first be sprayed on the adsorption layer through the spray nozzle, which can realize the adsorption and enrichment of specific organic substances, and helps to extract the target components from the complex mixture. The permeation layer is arranged below the adsorption layer. When the impurities are adsorbed, the mixed solution will flow onto the permeation layer, and separation is achieved on the permeation layer to separate the target organic chemical raw material components. By combining this adsorption function with the separation function, the separation effect is further improved. Compared with the distillation method, the purity of the extraction of the target organic chemical raw material components is improved.

[0016] 2. By arranging the adsorption layer in an arc shape in the present utility model, when the spray nozzle sprays the mixture on the adsorption layer, the spray nozzle is located directly above the adsorption layer, so that the mixture solution can flow to both sides on the adsorption layer, increasing the contact area between the adsorption layer and the solution, and improving the adsorption capacity of the adsorption layer.

[0017] 3. By arranging a lapping platform inside the separation box of the present utility model, the permeation layer is movably arranged on the lapping platform through the lapping plate. There is a sealing plate at the opening of the separation box. After the mixture is separated, by opening the sealing plate and pulling out the second membrane shell, the permeation layer can be replaced, and the isolated impurity liquid can also flow out through the discharge port.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] As Figures 1 to 6 shown, the present utility model provides an extraction and separation device for organic chemical raw material components, which includes a separation box 1. Lapping tables 2 are provided on the opposite inner surfaces of the separation box 1. The vertical cross-section of the lapping table 2 is "L"-shaped. An adsorption layer 3 and a permeation layer 4 are respectively provided on the lapping table 2. Both the adsorption layer 3 and the permeation layer 4 are membranes with driving pores.

[0027] The vertical cross-section of the adsorption layer 3 is arc-shaped and the adsorption layer 3 is located above the permeation layer 4. By setting the adsorption layer 3 in an arc shape, the mixed liquid can flow to both sides on the adsorption layer 3, thereby increasing the contact area with the mixture and improving the adsorption capacity.

[0028] A top cover 5 is provided on the top of the separation box 1. A vertical feed pipe 6 is provided on the top cover 5. A spray head 7 is provided at the bottom of the feed pipe 6. The spray head 7 is located inside the separation box 1 and directly above the adsorption layer 3, and can evenly spray the mixture on the adsorption layer 3 to achieve preliminary filtration of the mixture and effectively prevent blockage of the permeation layer 4.

[0029] On the inner wall bottom plate of the separation box 1, there is a through discharge port 8, and the target organic chemical raw material components can be collected through the discharge port 8.

[0030] On the opposite inner sides of the separation box 1, there are outward limiting grooves 9. On the side of the lapping platform 2 close to the separation box 1, there is a clamping strip 10. The clamping strip 10 is inserted into the limiting groove 9, which can fix the lapping platform 2 in the limiting groove 9 through the clamping strip 10, ensuring the fixed positions of the two lapping platforms 2.

[0031] On the lapping platform 2, there are a first lapping groove 11 and a second lapping groove 12. On the top of the adsorption layer 3, there is a first membrane shell 13. On the bottom of the adsorption layer 3, there is a grille 14, enabling the mixture solution to flow through the voids of the grille 14 onto the permeation layer 4 after passing through the adsorption layer 3. The vertical cross-section of the grille 14 is also arc-shaped, and the grille 14 and the first membrane shell 13 fix the adsorption layer 3.

[0032] On both side walls of the first membrane shell 13, there are symmetrically arranged insertion plates 15. The insertion plates 15 are movably embedded into the first lapping groove 11. The insertion plates 15 are movably inserted into the first lapping groove 11, which can fix the adsorption layer 3 and is also convenient for taking it up.

[0033] The permeation membranes on the permeation layer 4 are multi-layered. Outside the permeation layer 4, there is a second membrane shell 16. On the two side walls of the second membrane shell 16, there are lapping plates 17. The bottom of the lapping plates 17 forms a rear semi-circular part 18. The semi-circular part 18 is movably located in the second lapping groove 12, ensuring that the permeation layer 4 does not move during the separation and extraction of the mixture, guaranteeing stability.

[0034] On the surface of the separation box 1 perpendicular to the lapping platform 2, there is an opening. The opening is located at the position of the permeation layer 4. Inside the opening, there is a sealing plate 19 connected movably. The sealing plate 19 can be locked at the opening position of the separation box 1 by screws or other means.

[0035] On the side of the sealing plate 19 close to the permeation layer 4, there is an elastic sealing gasket 20. When the elastic sealing gasket 20 seals the opening, it can completely fit with the second membrane shell 16, preventing the mixed solution from flowing down through the gap without being separated and improving the stability of separation and purification. On the other side of the sealing plate 19, there is a handle 21.

[0036] On the inner bottom plate of the separation box 1, there are symmetrically formed inclined chutes 22. The lowest point of the inclined surface of the inclined chutes 22 is located at the discharge port 8, enabling the separated organic chemical raw material components to flow out of the discharge port 8 better and realizing the collection of the organic chemical raw material components.

[0037] The detailed usage method and functions of the above embodiments:

[0038] When it is necessary to collect the components of organic chemical raw materials, open the top cover 5 of the separation box 1, fix the permeation layer 4 on the second membrane housing 16, fix the adsorption layer 3 between the first membrane housing 13 and the grille 14. There are clamping strips 10 on both sides of the overlapping platform 2. Insert the clamping strips 10 into the limiting grooves 9 to fix the overlapping strips. Place the permeation layer 4. There are overlapping plates 17 on both sides of the second membrane housing 16. The semi-circular parts 18 of the overlapping plates 17 cooperate with the second overlapping grooves 12. Then place the adsorption layer 3 so that the clamping strips 10 are inserted into the first overlapping grooves 11. After the installation is completed, cover the top cover 5.

[0039] Put the mixture solution into the feed pipe 6, and it will be sprayed on the adsorption layer 3 through the spray head 7. The adsorption layer 3 will adsorb and enrich specific organic substances, making them stay on the adsorption layer 3. The remaining mixed liquid will flow through the adsorption layer 3 to the permeation layer 4. The permeation layer 4 is composed of multiple permeation membranes. Only the target components of organic chemical raw materials can pass through the permeation membranes, and others cannot. Finally, the solution of the components of organic chemical raw materials will flow out from the discharge port 8. After collecting the components of organic chemical raw materials, open the sealing plate 19 and pull out the second membrane housing 16 to replace the permeation layer 4. The remaining impurity solution will flow out through the discharge port 8 again.
